    Abstract: 本論文使用計算流體力學(Computational Fluid Dynamics,CFD)軟體FLUENT配合一系列使用者自定函數(User Defined Function, UDF)完成二氧化碳合成甲醇之填充床式觸媒反應器(Packed Bed Catalytic Reactor,PBR)與觸媒薄膜反應器(Catalytic Membrane Reactor,CMR)之三維模式模擬,模式納入了填充床球型觸媒顆粒反應器中巨相、觸媒顆粒內、巨相與觸媒顆粒間、薄膜兩側巨相間之流力、熱傳與質傳及觸媒顆粒內之化學反應。流體速度限制於層流範圍。 透過模擬探討了反應器內部之壓力、速度、溫度與組成分佈,並探討觸媒顆粒孔徑、粒徑、操作壓力、進料流量、是否具薄膜與膜厚等參數之影響。針對填充床之摩擦因子以及觸媒顆粒與巨氣相間之熱傳係數與質傳係數,本研究並比較模擬結果與文獻關聯式,結果顯示摩擦因子較吻合,熱傳係數與質傳係數則有極大差異。
